Value of √961 by Long Division Method
Explanation:Forming pairs: 09 and 61Find a number Y (3) such that whose square is Bring down the next pair 61, to the right of the remainder 0. The new dividend is now 61.Add the last digit of the quotient (3) to the divisor (3) i.e. 3 + 3 = 6. To the right of 6, find a digit Z (which is 1) such that 6Z × Z Divide 61 by 61 with the quotient as 1, giving the remainder = 61 - 61 × 1 = 61 - 61 = 0.We stop the process since the remainder is now 0 and there are no more digits that can be brought down.
Therefore, the square root of 961 by long division method is 31.
Is Square Root of 961 Rational?
